HV-EV VEHICLE TECNOLOGY Develop a numerical model of a Series Hybrid Scooter (with Range Extender) and of a Parallel Hybrid Scooter Suite of software tools for hybrid scooter design has been developed in order to analyse and optimize the electric driveline in terms of operating strategies, driving mode and fuel consumption/acceleration performances MOTORCYCLE Services CHATTERING BRAKING REDUCTION 1. ON-ROAD TIRE LONGITUDINAL BEHAVIOUR IDENTIFICATION Investigate low speed braking vibration 2. LONGITUDINAL TIRE BEHAVIOUR phenomena; define the adequate AS FUNCTION OF TIRE OPERATIVE CONDITIONS methodological chain; implement a CAE to simulate non linear dynamic behaviour 3. LONGITUDINAL TIRE BEHAVIOUR IN REAL DRIVING CONDITIONS Optimization of frame design and increased 4. WEAR ALGORITHM PREDICTION stability and safety. Development of a new CAE model to predict the dynamic behaviour of the system DRIVABILITY CHARACTERIZATION COMFORT CHARACTERIZATION STRUCTURAL VIBRATION REDUCTION Develop a new synergy between pilot and To minimize sensitivity to any disturb that Reduce structural vibration caused by vehicle in order to improve safety and can affect vehicle riding during daily usage engine inertia unbalances via engine mounts motorcycle drivability layout optimization Characterization methodology to support the comfort evaluation. The objectification Methodology has been created to optimize Suite of software tools has been provided and process output is a set of objective metrics, the engine mounts layout (numbers, the mutual interaction between driver and suitable for solution design and direct settings positions) in order to reduce the vibrations motorcycle has been implemented into codes comparison (road irregularity absorption, transmitted to the chassis. CAE tool has been to optimize drivability in function of different thermal comfort, aerodynamic comfort, developed, able to handle both rigid and driving styles. ergonomics, engine vibrations, etc.). deformable chassis via FEM integration STABILITY CHARACTERIZATION SUSPENSION OPTIMIZATION ENGINE HANGER DESIGN Analyse the mutual dynamic interaction To speed-up both the suspension design and Provide methodology to design engine between driver and motorcycle in order to the tuning process hanger mounts to improve comfort and objectify driving style and driver perception handling performances A vehicle-indipendent methodology has been Objectification of driving style to assist created to optimize stiffness/damping Methodology to design hanger mounts vehicle design and tuning: driver feeling and suspensions parameters using a CAE tool (position, geometrical data, stiffness) has been driving style become key parameters to (OptimSuspension®) interface. Very good provided and specific optimization codes has define the best setup (tires, frame stiffness, results achieved on suspension optimized been implemented suspension..) to satisfy the driver target-class prototype concerning riding comfort. expectation
